It works using your suggestion. Thank you. Do you happen to know what is the exact mathematical formula f(x) for the gamma correction and how the two following parameters are used ?

imgdata.params.gamm[0]
imgdata.params.gamm[1]

I reckon the first one is the power and the second one is the toe. I have no clues for the second one. Also I suppose that the variable x range should be between 0 and 1. I may have to reuse the gamma correction in a separate process later down the processing pipeline. Thank you very much.
